Description

Technical Field

[0001] This utility model belongs to the technical field of waterproof manhole cover equipment for culverts, and specifically relates to a steam culvert waterproof composite manhole cover. Background Technology

[0002] Steam transmission culverts are mainly used for the laying of steam pipelines to ensure reliable steam transmission. At present, the composite manhole covers used in steam culverts are often not completely sealed in order to meet the culvert's venting requirements. Most of them use metal manhole covers, cement concrete manhole covers, resin manhole covers, etc. These manhole covers have poor sealing and waterproof performance. During the flood season or large-scale drainage, a large amount of water often enters the culvert, which seriously threatens the safe operation of the steam pipeline.

[0003] In summary, how to solve the problem of poor sealing and waterproofing performance of traditional steam conveying culvert covers, so that they have self-sealing and waterproofing functions without affecting ventilation and exhaust in daily life, has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof composite well cover for steam culverts to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A waterproof composite manhole cover for steam culverts includes a manhole cover and a manhole cover base. The manhole cover base is located below the manhole cover, and the manhole cover is installed on the manhole cover base. The manhole cover has a plurality of drainage holes evenly distributed on it. The manhole cover base has a plurality of fixing seats evenly distributed below it. The fixing seats have pin holes, and the fixing seats have self-sealing buckles that are matched with the drainage holes by means of pins passing through the pin holes.

[0007] Preferably, the self-sealing buckle is an L-shaped structure with an angle of 100 degrees. 。 -140 。 between.

[0008] Preferably, one end of the self-sealing buckle is provided with a sealing gasket, the size of which matches the drain hole. The middle position of the self-sealing buckle is installed on the fixing base through the pin hole using a pin. The other end of the self-sealing buckle is provided with a connecting rod, and the other end of the connecting rod is connected to a water collection tank.

[0009] Preferably, the outer diameter of the water collection tank is larger than the outer diameter of the drain hole, and a bottom drain reset swivel is provided at the middle position of the bottom of the water collection tank.

[0010] Preferably, the fixing base, self-sealing buckle, connecting rod and water collection tank are all made of high temperature resistant and corrosion resistant composite materials.

[0011] Preferably, the manhole cover base is provided with a positioning groove, the size of which matches the perimeter of the manhole cover.

[0012] The beneficial effects of this utility model are as follows:

[0013] This device features an L-shaped self-sealing buckle movably mounted on the base of the manhole cover using a pin. A water collection trough is connected to the bottom of the buckle via a connecting rod. The weight of the water in the trough causes the L-shaped buckle to rotate, sealing the drainage hole on the manhole cover with a sealing gasket at one end. Its simple structure and effective use, along with its simple mechanical design, seal the drainage hole without affecting ventilation. This solves the problem of large amounts of water entering the culvert during flood season or major drainage events, which seriously threatens the safe operation of steam pipelines.

[0017] The present invention will be further described below with reference to its specific structure and usage:

[0018] like Figure 1 and 2 The illustration shows a waterproof composite manhole cover for a steam culvert, comprising a manhole cover 1 and a manhole cover base 3. The manhole cover 1 is mounted on the manhole cover base 3, and the manhole cover 1 has several drainage holes 2 evenly distributed on it for daily ventilation of the steam transport culvert. Several fixing seats 4 are evenly distributed below the manhole cover base 3, and each fixing seat 4 has a pin hole 6. A self-sealing buckle 5 is installed on the fixing seat 4 via a pin through the pin hole 6. The pin connection and clearance fit ensure flexible operation and convenient assembly / disassembly. The self-sealing buckle 5 matches the drainage holes 2. The self-sealing buckle 5 is an L-shaped structure with an angle of 100 degrees. 。 -140 。Between the two, after the action, its sealing gasket 10 is parallel to the drain hole 2, with accurate alignment and excellent sealing effect, preventing water from flowing in again. One end of the self-sealing buckle 5 is provided with a sealing gasket 10, the size of which matches the drain hole 2. Generally, the size of the sealing gasket 10 is slightly larger than the size of the drain hole 2, so that its sealing effect reaches the best state. The middle position of the self-sealing buckle 5 is installed on the fixing base 4 through the pin hole 6 using a pin. The other end of the self-sealing buckle 5 is provided with a connecting rod 7, and the other end of the connecting rod 7 is connected to the water collection tank 8. The self-sealing buckle 5 and the water collection tank 8 are balanced by their own weight, ensuring unobstructed ventilation and exhaust of the drain hole.

[0019] The outer diameter of the water collection tank 8 is larger than the outer diameter of the drain hole 2 to ensure water collection effect, so that the water discharged into the drain hole 2 can be concentrated in the water collection tank 8, preventing leakage into the steam duct. The bottom of the water collection tank 8 is provided with a bottom drain reset swivel 9 in the middle position for quick drainage and restoration of the equipment to normal state.

[0020] The fixed base 4, self-sealing buckle 5, connecting rod 7 and water collection tank 8 are all made of high temperature resistant and rust-resistant composite materials, which increases their service life and ensures their reliable operation.

[0021] The manhole cover base 3 is provided with a positioning groove. The size of the positioning groove matches the perimeter of the manhole cover 1, so that the manhole cover can be quickly and easily installed in the manhole cover base 3. At the same time, the purpose of matching the size of the positioning groove with the perimeter of the manhole cover 1 is to make the manhole cover 1 and the manhole cover base 3 fit together, which plays a waterproof role and prevents water from flowing into the steam culvert from the perimeter of the manhole cover 1.

[0022] In use, the device is installed on the manhole cover of the steam culvert. It typically has four drainage holes 2 and four corresponding self-sealing buckles 5. Ventilation and exhaust are achieved through the drainage holes 2. During flood season or periods of heavy drainage, water flows through the drainage holes 2 into the manhole cover 1, then collects in the water collection trough 8. As the water volume increases, breaking the gravitational balance between the water collection trough 8 and the self-sealing buckles 5, the self-sealing buckles 5 engage with the fixing seat 4. The water collection trough 8 sinks after collecting water, causing the connecting rod 7 to move. The connecting rod 7 then rotates the self-sealing buckle 5 around the pin in the pin hole 6 on the fixing seat 4 until the sealing gasket 10 at the other end of the self-sealing buckle 5 moves upward. The sealing gasket 10 becomes parallel to and contacts the drainage hole 2, sealing the drain outlet 2 and achieving a self-sealing waterproof effect, preventing water from entering the culvert and causing safety issues for the steam pipeline operation. After the flood season issues are resolved, open the manhole cover 1, and then use the bottom drainage reset swivel 9 of the water collection tank 8 to drain the water in the water collection tank 8 and restore the equipment to normal operation.
